Installation and configuration

Did you test an app with prefix?
https://wiki.ubuntu.com/Ayatana/ScrollBars

Maybe try configure with gtk3; websearch found this package.
https://aur.archlinux.org/packages.php?ID=50116

Another idea getting from there
http://www.webupd8.org/2011/04/how-to-disable-overlay-scrollbars-in.html

which suggests a cmd how to disable overlay-scrollbar, so instead maybe the contrary works.
echo "export LIBOVERLAY_SCROLLBAR=1" > /etc/X11/Xsession.d/80overlayscrollbars

Thanks Sam

I tried #1 and #3 already (they are the same). As for #2, there is also a gtk2 version of the package https://aur.archlinux.org/packages.php?ID=48816 so it should work with gtk2 as well, I think. But both the packages are actually patched gtk(2/3). Do I have to patch my gtk as well?

That's a very good question, is there a 'readme' where it states it's necessary?
Maybe contact ayatana team.

Its not the readme Sam, both the archlinux packages are patched gtks. Thanks for your help. I put a message with Scrollbars team owner.

Ubuntu patched GTK, so all scrolled windows automatically used the overlay scrollbar. Else you have to change the sourcecod of all applications.

You can find the Patch here: https://launchpad.net/ubuntu/oneiric/+source/gtk+2.0/2.24.5-0ubuntu2

Download gtk+2.0_2.24.5-0ubuntu2.debian.tar.gz (139.8 KiB), then applay the patch debian/patches/100_overlay_scrollbar_loading.patch to your GTK source, recompile GTK (only 2 or 3 files are changed).

Restart and you should have overlay scrollbar in the most applications.

I didn't test this, but I'm a developer and I used the overlay scrollbar in my own application;-)

Hi,

I have managed to compile the patched gtk2 with the latest overlay patch.
The overlay-scrollbars are working within gtk2 apps.

I also tried to patch the latest gtk3 version (3.4.3), but I cannot apply the provided 100_overlay_scrollbar patch file.
Is this not needed anymore?

It compiles without the patch, but the overlay-scrollbars are not working..

Could someone please help?

Running on Archlinux.

Thanks!
